Optimizing Indoor Agriculture: Leveraging the Power of UVA Spectrum

Optimizing Indoor Agriculture: Leveraging the Power of UVA Spectrum

Indoor agriculture faces a challenge in delivering visually appealing, nutritious crops without natural sunlight. To overcome this, leveraging UVA spectrum light offers a promising solution. Research shows that controlled UVA exposure enhances fruit ripening, improving sweetness and flavor. Integrating UVA optimization into indoor farming practices can elevate crop quality, meeting consumer preferences effectively.

What is TM-30-15 (TM-30-18), and should I use it?

What is TM-30-15 (TM-30-18), and should I use it?

TM-30-15 is a color rendering index system published by IES (Illuminating Engineering Society).  A color rendering index system indicates how well a light, when shining on objects, can reproduce the object’s color accurately (compared to a black body radiator – e.g., the sun).  TM-30-15 is next in a line of predecessor CRI systems (CIE CRI, GAI, CQS), each intended to improve on previous designs.  In this article, we explain TM-30-15, its advantages, and why it’s important.

Automated LED Calibration for Cinema-Stage Light Manufacturing

Automated LED Calibration for Cinema-Stage Light Manufacturing

Cinema LED light manufacturers use what are called “ratio tables” to calibrate their LED lights. This mostly manual process is time consuming, tedious and prone to errors. In this article we will introduce automated LED calibration as a way to speed up calibration many times over and ensure precision color accuracy according to CIE 1931 standards.

What is CRI (Color Rendering Index)?

What is CRI (Color Rendering Index)?

What is CRI (Color Rendering Index)? It is a metric used to measure the ability of a light to bring out colors in objects (i.e. Color Rendering). Lights with a high CRI rating can make store products look brilliant and vibrant. Other lights with low CRI ratings will make the same products drab and lifeless.
